My invention relates to clothes wringers and has reference particularly to the mechanism' whereby the upper roll is mounted in position and held at a tension against the lower roll.

The principal objects ,of my invention are to provide improved means for clamping the upper roll in place; to permit independent removal of the upper roll from the wringer frame when the clamping means is released; to afford a release which is so prominent and extensive and easy to operate that release of the pressure between the rolls is assured in an emergency and thesafety of the wringer greatly increased; to 'hold the upper roll in place by means of a frame which swings transversely ot the rolls; to provide an improved drain-board construction wherein the drain-board is readily shifted to opposite positions; and in general, to provide an improved wringer construction of simple form and light weight, which is economical to manufacture and conveniently assembled.

Fig. a side View ci a lwringer partly in section showing a modied form of connl struction.

`Referring to the. drawings; the numerals 1 and 2 indicate the end' castings of the main frame which are oppositely arranged and connected together bytie rods 3 at each side of the wringer, said rods being passed through apertures in laterallyl projecting view taken on the line bosses 4 of the end castings 1 and 2, and secured in place by nuts 5 which are threaded on the rods. The end castings 1 and 2 are of similar construction, each comprising a semi-circular flange 6 with bearing portions 7 extending upwardly from the opposite end thereof, as shown particularly in 5 and 6, and reinforced and connected webs 8 and 8 to the bosses 4., Extending outwardly from' each end casting 1 and 2 are the bosses 9 and 10 respectively which are arranged concentric with the semi-circular liange 6 and turned down eiiternally, as at l1 and 12 res ectively, to ador-d bearings upon which t e swinging frame of the wringer is pivoted. 'lheboss 9 ofthe casting 1 proiects outwardly a greater distance than the boss 10 ofthe casting 2 to a-.ilord a connection with a bracket 13, whereby'the wringerl is supported, and both the bosses 9 and 10 are bored out as at 14 and 15 respectively to loosely receive the ends of the shaft 16 of the lower wringer roll 17, said shaft being journaled in bearing blocks 18, preferably of wood, which are supported on the semi-circular ange 6 of the respective end casting 1 and 2 between'the flanges 7 thereo.

rlhe upper Wringer roll which is indicated at 19 is ixed on the shaft 20, which has the ends 'journaled in bearing blocks 21., which latter are retained on the shaft by riveting over the ends of the shaft as indicated at 'c 22. The bearing blocks 21 slide into the upper ends of the main frame end castings 1 and 2 between the flanges 7, and hold the roll 19 in )roper position above the lower roll 17, su `cient clearance being .provided between the upper and lower bearing blocks 21 and 18 so that the upper roll 19 bears directly upon the lower roll 17, and when the clamping mechanism hereinafter' described, which holds the upper roll in place, is released the upper roll 19 together with the bearing blocks 21 ma be lifted out and entirely removed from tie wringer.

n the preferred construction, there is a gear connection between the rolls 17 and 1.9 consisting of intermeshing gears 23 and 24 on the shafts 16 and 20 respectively, and to accommodate this gearing a U-shaped housing 25 is mounted by means of boxes against the inner face of the housing and the inner face of the end casting 2, these plates being secured` in place by bosses 28 thereon, which are apertured to receive the rods 3, and clamped 1n place by the nuts 5. Each plate is rovided on its inner face with a U-shapeti flange 29 whichserves as a guard to embrace the ends of the upper and lower wringer rolls and prevent the clothes running out beyond the ends of the latter, and each of these plates also has a slot 30 extending downwardly from the top thereof between the side portions of the vflange 29 to admit the shafts of the upper and lower Wringer rolls.

If desired the gears 23 and 24 may be omitted as shown in the modified form of Fig. 10, and if so, the housing 25 is also omitted and the cover plate 27 clamped di rectly against the inner face of the end casting 1 the same asat the opposite end of the wringer.

A spring housing 31 is mounted at each end of the wringer on the bearings 11 and 12 respectively, and each of said housings comprises a bearing loop 32 at the lower end embracing the respective bearings 11 or 12 of the end castings 1 or 2, and having spaced side Walls 33 extending upwardly and connected together at their upper ends by a top wall 34. 'A bar 35 extends between and is connected to the upper ends of the spring housings 31 to form, with the latter, a swinging frame for releasably holding the upper roll 19 in place, said bar be ing preferably formed oi sheet metal stamped insemi-circular cross section and' .with flattened ends which are secured to the top walls 34 of the spring housings 31 by cap screws 36. The side walls ot' each spring housing have inturned flanges 37 extending along the inner edges thereof and serving as guides for a sliding plate 38 which has offset portions 39 and 40 at the opposite ends respectively thereof and upon opposite sides of the flanges 37, 'lhe portion 40 at the lower end ot the plate 38 forms a seat for the lower end ot a compression spring 41 which is held in place on'the seat by a projection 42 on the latter which lits into the lower end of the spring 41. A plug 43 is' inserted into the upper end of the spring 41and' has a annular iange 44- bearmg against the upper end ot the spring, A

and this plug has a recess 45 arranged cen trally in the top which is engaged by the lower end of the adjusting screw 46 which is threaded through the 'top wall 34 of the spring housing. The portion 39 at the upper end of the sliding plate 38 is arranged to project inwardly over the top et the ad-I joining end casting 1 or 2 ot the main trame, and has' a slot therein within which a roller 47 is mounted on a pin 48 so as to roll up onto the top oit the bearing block 21 as the manera swinging frame is lswung to the-upright position, and thereby appl the tension of thev springs 4l onto the en bearings 21 for resiliently .holding the upper roll.19 down k,the roller 47 as it is moved up onto the bearing block from either side of the wringer, and .these faces 49 terminate in a shallow recess or roller seat 50 which is engaged by the roller 47 under spring tension` when the swinging frame is in the upright position and releasably holds said frame in the'upright position.

The bearing blocks 21 are preferably surrounded by a metal shell 51 to withstand .the wear occasioned by the sliding action along the retaining flanges 7 and the operation of the roller on the top face, and said bearing blocks may be similarly constructed with .inclined laces and roller seat atthe bottom as shown by dotted lines-at 52 in Fig. 5, so that said blocks may be reversed to ,permit excessive wear of the shaft 20 at one side of the bearing opening of the block 21. The lower bearing blocks 18 may also be round if desired, as shown by dotted lines at 53 in lFig. 5 to permit adjustment for the same pur ose. 1'.-

1F urthermore, may employ round bearing blocks 54,- as shown in Fig. 9, on the shaft 20 instead ot the bearing blocks 21, and in such case the plate 38 4is provided with a projection 55 at the up r end with a pair ot' spaced rollers 56 Wluc i straddle the bearing block 54 when the swinging :trame is in the 'upright position and thereby releasably hold. the said trame in the upright position.

To limit 'the swinging. movement of the swinging frame the bosses 9 and 10 of the castings 1 and 2 are formed with a thickened portion 57, as shown in Fig. 7, terminating in shoulders 58 which are adapted to be engaged by the lowerends of the side walls 53 of the spring housing 31 when the swinging frame is thrown laterally as feras required.

llt it is desired to close the top ot' the gear housing 25 when the wringer is i1S- sembled, a plate 59 shown b dotted line in Fig. 2, may be secured to t e bearing 31 and provided with an out-turned portion 60 at the upper end which lits into the upper end of the gear housing 25.

lln connection with this wringer, I have also provided an improved drain pan which ilu is more convenient to adjust for draining at opposite sides of the wringer than drain pans which have heretofore been provided. An arm 61 is secured to the lower end of one of the end castings 1 or 2, preferably to the one adjacent the bracket connection 13, and this arm projects inwardly as shown, to a distance somewhat beyond the center of the wringer roll 17. The drain pan 62 which is provided with upturned flanges 63 at the opposite ends, is provided with a stamped depression 64 midway between its ends, forming a bearing face 65 which rests fiat upon the top of the arm 61 and holds the drain pan at the proper inclination, the drain pan being held on the arm by a bolt 66 which is passed. through an aperture in the portion 65 and through an aperture in the arm 61 midway between the ends of the wringer roll, and on the lower end of the bolt I provide a lock washer which is clamped betweerf fa pair of plain washers 68 by the nut 69 at a suitable tension'to yieldingly hold the drain pan 62 down on the arm 61. At the inner end of the arm 59,

.there is a pin 70 which projects upwardly,

and is adapted to engage in either of the corrugations 71 which are provided adjacent the opposite ends of the drain pan for lockingr the latter in either of the two positions to which it is adapted to be adjusted. With this construction when it is desired to swing the drain pan around to drain at the opposite side of the wringer, the end of the drain pan adjacent the casting 1 is lifted so as to disengage the corrugation 71 from the' pin 70, the resiliency of the spi'ing washer 67 being suicient to permit the lifting of this end of the drain pan to release same from the pin. The drain pan is then swung around to the reversed position wherein the corrugation 71 at the opposite end of the pan is broughtl into engagement with the pin 70 and interlocked therewith to hold the drain pan in the newly adjusted position.

From the foregoing it will be observed that the upper roll 19 with its bearings 21 is held in place by the swinging frame com prising the top bar 35 and; spring housings.

31 which may be thrown in either direction to release the upper roll, and as the swinging frame rcachesentirely across the top of the wringer and down the sides thereof and may be shifted by pressures applied at any point, it is easy to operate in an emergency and affords greater safety than any wringer heretofore constructed of which I am aware.

Furthermore, unlimited separation of-the rolls is permitted when the swinging frame is released as the upper roll with its end bearings may be entirely removed from the wringer frame.
